I hope that USA will give the spot to Kaetlyn Osmond instead of Alissa Czisny who is injured :(

With Kaetlyn Osmond in the mix, it would be a fantastic competition, really it would be a strong field :D

First of all, the USFSA can't "give" Czisny's spot to anyone, they're not the event organizers. At most they can free a spot so that someone else can get assigned (though at this late date, that might not happen either). Second, even if they could give the spot to a specific skater, why would it be in their interest to do that for a Canadian skater? I don't know if anyone will get the open slot, but I would be very surprised if it's Osmond, as it's also not in the best interest of the JSF to bring her in. She should be happy with her SC result and I will leave it at that.

I never expected Czisny to be ready for NHK, but I hope she will be able to compete in the second half of the season. Best of luck to her.

That's right. Dual citizenship is not allowed because most of "naturalized Japanese citizens" are from China and Korea. The Japanese government don't want them to use suffrage for the state that they don't trust.
